The BRK CO614B Plug-In CO Detector is the perfect solution when you do not want to mess with wired models, or do not have the capability to hardwire in your Carbon monoxide detector. With the BRK CO614B, you have the freedom to plug-in your detector instead of wiring it in, so you can place the detector where ever it may be most effective in your house. Equipped with a 9V battery backup, the BRK CO614B will operate smoothly even during power outage or loss. Additional features of this model include advanced patented electrochemical sensing technology, a 85db horn, a smart End of Life signal (chirps once per minute to tell you the battery is low and needs to be replaced), and a test / silence LED indicator light to show you the detector is armed ad ready.

The BRK CO614B has a digital display that will read the CO levels in your home visually.
